Philadelphia, PA, October 1, 2007 – Two studies in the October issue of the journal Gastroenterology may help in refining recommendations for the use of colonoscopy to screen for colorectal cancer.One study reports that patients with large polyps or adenomas—pre-cancerous growths that may develop into colorectal cancers—on initial colonoscopy may need more frequent follow-up, while those with only a few small polyps can be screened less often. The second study suggests that relatives of patients with large polyps should also be targeted for screening.
